In general use, a ferret is a domestic ferret (Mustela putorius furo). Several other small, elongated carnivorous mammals belonging to the family Mustelidae also have the word "ferret" in their common names, including the endangered black-footed ferret, but in common use, a "ferret" is a domesticated ferret.

Contrary to popular belief, ferrets are not rodents, but members of the mustelid family, which also includes weasels, stoats, and martens.

History

It is unknown exactly when ferrets were first domesticated, but ferret remains have been dated to 1500 BC.

Some say the ancient Egyptians had ferrets, but it is more likely that Europeans visiting Egypt saw cats and thought using a small carnivore to protect grain stores was a useful idea. The ancient Greeks kept pet ferrets: they are mentioned in Aristophanes's plays.

The ferret was most likely bred from the European Polecat (Mustela putorius), though it is also possible that ferrets come from the Steppe polecat (Mustela eversmannii) or some hybridization thereof.

Wild ferrets, in the form of ferret-polecat hybrids, do still exist. New Zealand has the world's largest feral population of these hybrids. (See Ferrets as pests, below, for more details.)

Elizabeth I of England used to give ferrets as gifts, which were highly prized; a ferret is the mascot for the 1st Battalion the Prince of Wales's Own Regiment of Yorkshire in the British Armed Forces.

Ferreting

For hundreds of years, the main use of ferrets was for hunting, or ferreting. With their long, lean build and curious nature, ferrets are very well equipped for getting down holes and chasing rodents and rabbits ("rabbiting") out of their burrows. They are still used for hunting in some countries, including the United Kingdom and Australia, where rabbits are considered a plague species and the combination of a few small nets and a ferret or two remains very effective despite technological advances. However, the practice is illegal in several countries, where it is feared that ferreting could unbalance the ecology.

Caesar Augustus sent ferrets (named "viverrae" by Plinius) to the Balearic Islands to control the rabbit plagues in 6 BC.

Ferrets were first brought to the New World in the 17th century and were used extensively from 1860 until the start of World War II to protect grain stores in the American West. They first became popular as pets in the mid-1970s, chiefly thanks to Dr. Wendy Winstead, a veterinarian and former folk singer who sold ferrets to a number of celebrities and made many TV appearances with her own ferrets.

Ferrets as pets

Ferrets sleeping in a pile

In many ways, ferrets act like kittens that never grow up. They have energy, curiosity, and are always interested in their surroundings. They are also considerably more people-oriented than cats, and actively elicit play with their owners.

It is important for a ferret owner to handle a young ferret correctly. Ferrets tend to be very nippy as kits, requiring patience and persistence in handling. Nipping is the act of biting in a playful manner reminiscent of mock fighting and sparring; young ferrets are also more prone to chewing and teething. Older ferrets tend to chew far less frequently and when trained correctly, almost never nip a human hand. Younger inexperienced ferrets have a tendency to nip and bite harder, which may irritate an owner who does not understand ferret behavior. For this reason, some young ferrets end up neglected, when owner patience runs out and the ferret is abandoned to its cage.

Ferret lifespan can vary widely, but usually falls between six and ten years, though in rare cases they can live into their early teens. While there are two types of ferrets, the European and the Black-Footed, it is the European ferret that is the widely domesticated species. Thus it is the European ferret that breeders breed in order to turn a profit through the sale of the animals as pets.

In the USA ferrets typically cost around $100 to $150. Additional costs of a secure cage, food, bedding, veterinary check-ups, and medicine should be taken into consideration by prospective owners.

Dangers to ferrets

It has been suggested that ferrets were bred for curiosity; whether this is true or not, their curiosity often exceeds their common sense. Ferrets are very good at getting into holes in walls, cupboards, or behind household appliances, where they can be injured or killed by electrical wiring, fans, and other dangerous items. Many enjoy chewing items made of soft rubber, foam, or sponge, which present the risk of intestinal blockage and death if ingested. Serious and sometimes fatal injuries have resulted from ferrets chewing on electrical cords. Screen doors can be damaged by a ferret's claws, and dryer vents often become escape routes to the outdoors. Unlike dogs and cats, most lost ferrets have little homing instinct and cannot survive as strays, usually causing them to die of dehydration within a few days unless found.

Recliners are a leading cause of accidental death in ferrets. Ferrets will often climb inside the springs and then be squashed and injured or killed once the chair is put into a reclined position. Fold-out sofas cause similar problems.

For these reasons, steps must be taken to "ferret-proof" a home before acquiring one as a pet. Ferret-proofing a house is an ongoing task that involves carefully going through each room, removing items dangerous to ferrets and covering over any holes or potential escape routes. As ferrets can open improperly latched cupboards or doors by rolling over and clawing at the bottom edge, many owners buy childproof latches or keep cleaning products in high, out-of-reach places. However, ferrets can typically fit through any hole as small as the size of their head, making some childproof latches ineffective.

Diet

Ferrets are obligate carnivores; their natural diet consists of whole small prey--meat, organs, raw bones--not just meat, and they lack the ability to digest vegetable matter.

There are a wide variety of ferret foods available at pet shops worldwide. A dry kitten food can also be used, as long as it provides the high protein and fat content required by the ferret's metabolism. However, most adult cat foods and many kitten foods lack the nutrition that ferrets require, as ferrets require more protein in their diets than cats. Low quality pet foods often contain grain-based protein which ferrets cannot properly digest. Ideally, a ferret food should contain between 32-38% protein and between 15-20% fat, with the top three ingredients meat-based.

Ferrets usually have a fondness for sweets like raisins, bananas, peanut butter, and pieces of cereal. Such treats should be given sparingly (if at all), as their high sugar content has been linked to insulinoma and other diseases. In fact, veterinarians suggest not feeding raisins and the like to ferrets at all because they are known to hide their food, raising the possibility of a ferret hiding a large amount of raisins over time and then dangerously consuming them all at once.

Some ferret owners feed a meat-based diet consisting of chicken, organs, bone, and whole prey like mice and rats. This is still common in Europe, and is becoming increasingly popular in the US as concerns are raised about processed ferret foods' high sugar and carbohydrate content.

Feeding the Sick Ferret

If a ferret does not eat enough or loses too much weight, it is a good indication that the ferret is sick, and should be taken to a veterinarian. Sick ferrets and those recovering from an illness or surgery will often need to have their diet supplemented. Often hand-feeding or, in extreme cases, force feeding may be necessary. This should not be undertaken without the advice of a veterinarian. Many recipes are available for feeding sick ferrets. They are informally known as "duck soup". A few recipes follow:

Baby Food:

• An all-meat baby food such as Gerbers Chicken can by itself make a good supplement. Reading the ingredients and checking with a veterinarian is essential however because many baby foods have vegetable ingredients which are inappropriate and some contain onions which are known to be toxic to dogs and cats.

Easy Soup:

• Ferret kibble soaked in chicken broth or water
• Gerbers Chicken baby food
• Ferretone, Ferretvite or a similar vitamin supplement
• Blend it all up and serve warm.

Tasty, Good Soup:

• Whole boiled chicken ( pull the meat and some fat off.) Reserve the boiled broth for the next step.
• Put just a little bit of the meat and fat into a blender and pour some broth into it and puree it until soup and *do it to all of the meat until all is blended and soupy. An easy way to freeze the soup is pour into icetray and *when time to serve a cube out and pop in the microwave. Soup should be served warm.

Activity

Ferrets spend 14 to 18 hours a day sleeping, but when awake they are very active, exploring their surroundings relentlessly. Ferrets are crepuscular, meaning they are most active during dawn and dusk. However, ferrets are known to easily adapt to the schedule of their owners. If kept in a cage, they should be let out for a few hours daily to get exercise and satisfy their curiosity. When ferrets are kept in their cages for too long, their walking ability can be affected, and they may become subject to depression or "cage stress." Ferrets, like cats, can use a litter box with training, though are not always totally litter box trainable.

Ferrets are also fine backyard companions and especially enjoy "helping" their owners in the garden. However, they should not be allowed to wander; ferrets are fearless to the point of foolishness and will get into whatever holes they will find, including storm drains. Whenever they are outside, they should be closely supervised and preferably kept on a harness leash designed for ferrets. There are different types of harnesses, and some ferrets prefer certain kinds. The H-shaped harness is the most popular. Collars will not work for ferrets as they do for dogs; a ferret can easily slip out of a collar because their heads are about the same width as their necks.

Additional care should be taken during mosquito and tick season, as ferrets are susceptible to the diseases carried by these parasites. Ticks can attach themselves and begin to draw blood. When the tick gets full, it regurgitates some blood and tick saliva back into the ferret, which is how Lyme and other diseases can be transmitted. Ordinarily, the regurgitation happens between five to 24 hours after the tick attaches. The key to keeping a ferret healthy is early removal of ticks using proper methods to avoid tick regurgitation, and prevention when in environments where encountering ticks is likely. Mosquitoes for their part can carry heart worms and the West Nile virus. Fleas can cause extreme skin irritation and can be intermediate hosts for tapeworms, one of which could potentially kill a ferret because of the ferret's small size. Also because of their small size, ferrets can also be regarded as prey by birds such as the hawk, and by larger snakes. Their small size also makes the venom of a bee, wasp or spider much more serious than for a larger mammal. For these reasons, an owner should be vigilant when a ferret is outdoors.

Play

Since ferrets are social animals, many of them are playful by nature and are happy to play with humans. Play for a ferret can involve hide-and-seek games, or some form of predator/prey game in which either the human attempts to catch the ferret or the ferret to catch the human.

Like a playful kitten, a ferret usually will not bite its human companions enough to cause pain, but will instead gently grab a toe or finger in their mouth and roll around with it. However, ferrets that have been abused or are in extreme pain will bite a human. Ferrets have strong bites and can sometimes bite through human skin, especially children's. Once properly socialized, however, domesticated ferrets will very rarely, if ever, bite humans.

Most kitten toys work well with ferrets. Toys made of rubber or foam should be avoided, however, as ferrets can chew off and swallow small pieces, possibly leading to intestinal blockage. Ferrets love playing tug of war with toys and stuffed animals.

Ferrets regularly wrestle with each other, and with their owners.

When ferrets are especially excited, they will perform the weasel war dance, a frenzied series of sideways hops. This is often accompanied by a soft chuckling noise, called dooking by many ferret owners.

Ferrets love to play and, besides eating and sleeping, spend most of their time doing it. They love to steal small items, so anything of special value must be kept out of their reach. Also, ferrets can drag and move things that are much bigger than they are.

Ferrets and children

File:Ferrets children.jpg

Child with ferrets

Ferrets can make good pets for children. However, like all other domesticated animals, they should not be allowed unsupervised near infants or very young children. There have been some cases where ferrets have severely injured babies, in one extreme case mauling a child's face. Given that young children and ferrets can both be excitable and prone to rough play, interaction between ferrets and young children must always be closely supervised -- for the protection of both the children and the ferrets.

It is important to note that this danger is often overstated. In comparison, dogs account for 800,000 bites annually that require medical attention in the US and 20 deaths per year.

Social nature

Ferrets at play

Ferrets are extremely social animals, and most enjoy playing and interacting with other ferrets. Many ferret owners recommend owning two or three ferrets for this reason, but there is nothing wrong with owning one ferret, provided that it receives lots of play time and attention. Ferrets frequently bond emotionally with other ferrets, and bonded pairs are often observed to die just a few days apart from each other.

Ferrets have been known to play with household cats and small non-aggressive dogs. However, great care must be taken when introducing ferrets to any new animal, particularly terriers and other breeds with instincts for catching ferret-sized prey. Ferrets will normally not get along with rabbits, birds, rats, mice, guinea pigs and small reptiles, some of which would have comprised part of their diet in the wild, and so may attack them given a chance.

Unusual Behaviors

Ferrets have a repertoire of unusual behaviors that can make them both endearing and difficult pets for some people. Ferrets enjoy picking up objects and carrying them off to "hidey holes". It is difficult to predict what objects a ferret will decide are worthy of hoarding, but in addition to play toys owners have found socks, 10 lb bags of onions, keys, calculators, silverware, sponges, etc... Ferrets will also tear open packages and other containers to see what is inside or explore the inside of the package. Ferrets have a strong interest in holes, pipes and other small enclosed areas. Ferrets seem compelled to explore holes. This makes them useful for ratting and tasks such as running pull lines through conduits but it also makes them prone to getting lost. Ferrets are also very curious animals and relatively fearless. This often puts them in situations where they will confront and try to play with large animals that are dangerous to the ferret. Ferret curiosity can also lead them to wander off past the point where they can find their way home. Though ferrets sleep more than almost all domesticated animals, they are usually very active when awake. Their energy level during play is almost frenetic and can be too much for many other pets, particularly older animals which may feel harassed by the ferret's tenacious attention.

The War Dance:

It is easy to confuse this invitation to play and/or expression of happy excitement with a threatening gesture. Posture becomes rigid with wide open jaws, momentary eye contact, followed by thrashing or turn of the head from side to side, arching the back, piloerection and hopping to the side or backwards while facing the intended playmate. This often accompanied by an excited-laughing panting sound that may sound like a hiss. If responded to appropriately, this behavior will usually break into a game of chase, pounce and wrestle. Ferrets in war dances are accident prone, often hopping into obstacles or tripping over their own feet to great comedic effect.

Care

Pet female ferrets should be spayed if they are not going to be bred. Ferrets go into extended heat and an unbred ferret without medical intervention can die of aplastic anemia.

Ferrets need their nails clipped and ears cleaned on a regular basis. Regular nail clippers will work, and most pet stores supply ferret specific ear cleaning solution. Most ferrets also shed twice a year, in the spring and fall; during this time, it is a good idea to brush them regularly and give them a laxative or petroleum jelly to help any ingested fur pass more easily through the digestive tract.

Frequent bathing is not necessary. Most sources recommend bathing no more frequently than once every 6 months, and many owners don't bathe their ferrets at all unless something needs to be washed off. Over-frequent bathing can actually increase a ferret's natural smell, as its skin works overtime to replace the oils lost in the bath.

It is a misconception that ferrets smell bad. The bad smell usually attributed to ferrets comes from their bedding and litter box. Bedding should be washed or changed out regularly, and a ferret's litter box should be cleaned every day, or at least every other day. Depending on the cage, it is a good idea to take it apart and hose it down every once in a while, to remove material stuck in crevices.

It is recommended that ferrets are taken to a veterinarian for a yearly checkup. Ferrets often hide symptoms of illness very well, perhaps from an instinct to not appear weak to predators in the wild. Any out-of-the-ordinary behavior is good cause for a consultation. Ferrets have high metabolisms and cancers can progress at an alarmingly fast rate. Early detection is critical.

Other uses of ferrets

Ferrets have been used to run wires and cables through large conduits. They have been employed in this way by event organizers in London. TV and sound cables were run by ferrets both for the wedding of Charles, Prince of Wales to Lady Diana Spencer, and for the "Party in the Park" concert held in Greenwich Park on Millennium Eve.

Since they share many anatomical and physiological features with humans, ferrets are extensively used as experimental subjects in biomedical research, in fields such as virology, reproductive physiology, anatomy, and endocrinology.

Ferret biology and health concerns

Like many other carnivores, ferrets have scent sacs near their anuses. Secretions from these are used in scent marking. It has been shown that ferrets can identify whether such a mark was left by a male or a female ferret, without recognizing the individual. Like a skunk, a ferret can release this scent when startled or scared, but the smell dissipates rapidly. Most pet ferrets in the US are sold with these anal sacs removed, although this does not affect a ferret's natural musky scent. To eliminate this scent entirely neutering male ferrets and spaying female ones is required, since it is through this odor that female and male ferrets find each other during the mating season.

In the UK it is illegal to remove a ferret's anal sacs without compelling medical reason, as it's otherwise considered to be an unnecessary mutilation.

Many domestic ferrets are known to suffer from several distinct health problems. Among the most common are cancers affecting the adrenal glands, pancreas, and lymphatic system. Certain breeds may also have a genetic defect known as Waardenburg syndrome .

Most ferrets will ultimately contract a life-threatening illness. It is uncommon for the domestic ferret to die from old age. Early detection and treatment of illnesses is the key to ensuring that ferrets live long and fun-filled lives.

Adrenal disease

Adrenal disease, a growth of the adrenal glands that can be either hyperplasia or cancer, is most often diagnosed by symptoms like unusual hair loss, increased aggression, and (in the case of females) an enlarged vulva. Even if the growth is benign, it can still cause a hormonal imbalance which can have devastating effects on the ferret's health.

Treatment options include surgery to excise the affected glands, melatonin implants, steroids and/or hormone therapy. The cause of adrenal disease is unknown, but speculated triggers include unnatural light cycles, diets based around processed ferret foods, and the premature desexing of pet-store ferrets. Others have suggested that the problem is hereditary.

Adrenal disease is usually detected during the spring or fall. This is because adrenal disease affects the hormones that make their fur grow, so when ferrets with adrenal disease shed their winter coat they simply don't grow it back because of the disease. The hair loss pattern is very specific for adrenal disease: It begins at the base of the tail and then continues up the ferret's back.

Insulinoma

Ferrets are also known to suffer from insulinoma, a cancer of the pancreas. The growth of cancerous nodules on the lobes of the pancreas sometimes, but not always, leads to an increase in the production of insulin, which regulates the rate at which the ferret's body metabolizes blood glucose. Too much insulin will cause blood sugar to drop, resulting in lethargy, seizures, and ultimately death. Symptoms of insulinoma include episodes of lethargy, drooling, pawing and/or foaming at the mouth, staring "blankly" into space, and seizures.

Like adrenal cancer, the exact cause of insulinoma is unknown. It is speculated that the diets of domestic ferrets are too far removed from the natural diets of their polecat ancestors, and include too much sugar or simple carbohydrates.

Treatment for insulinoma may include surgical excision of the cancerous lobes, pharmaceutical treatment with steroids that suppress the production of insulin, supplemental changes in diet (most often poultry-based baby food), or a combination thereof. Unfortunately, the growth of the tumors cannot be completely stopped, and the ferret will eventually suffer a reoccurrence of symptoms.

Lymphoma

Lymphoma/lymphosarcoma is the most common malignancy in ferrets. Ferret lymphosarcoma occurs in two forms -- juvenile lymphosarcoma, a fast-growing type that affects ferrets younger than two years, and adult lymphosarcoma, a slower growing form that affects ferrets four to seven years old.

In juvenile ferret lymphosarcoma, large, immature lymphocytes (lymphoblasts) rapidly invade the thymus and/or the organs of the abdominal cavity, particularly the liver and spleen. In adult ferret lymphosarcoma, the lymph nodes in the limbs and abdominal cavity become swollen early on due to invasion by small, mature lymphocytes. Invasion of organs, such as the liver, kidney, lungs, and spleen, occurs later on, and the disease may be far advanced before symptoms are noticeable.

As in humans, ferret lymphosarcoma can be treated surgically, with radiation therapy, chemotherapy or a combination thereof. The long-term prognosis is rarely bright, however, and this treatment is intended to improve quality of life with the disease.

Viral diseases

ECE (epizootic catarrhal enteritis), is a viral disease that first appeared in the northeastern US in 1994, is an inflammation of the mucous membranes in the intestine. In ferrets, the disease manifests itself as severe diarrhea (often of a bright green color), loss of appetite, and severe weight loss. The virus can be passed via fluids and indirectly between humans. Although it was often fatal when first discovered, ECE is less of a threat nowadays with the right supportive care.

ADV, the Aleutian disease virus, is a parvovirus originally found among mink in the Aleutian islands in the early 20th century. In ferrets, the virus affects the immune system (causing it to produce non-neutralizing antibodies) and many internal organs, particularly the kidneys. There is no cure or vaccine for the disease, and ferrets may carry the virus for months or years without any external symptoms. As a result, many ferret organizations and shelters recommend that owners test their pets for the virus regularly, separating them from other ferrets if they test positive.

Canine distemper is an extremely contagious virus that is almost always fatal. Being strict indoor pets does not necessarily protect ferrets as owners may bring the virus home on their clothes or their shoes. It is recommended that ferrets receive an annual vaccination. While this is vital to protect a ferret's health, it is not without controversy, and can cause anaphylactic shock. Some veterinarians prefer to pre-treat ferrets with injectable benadryl. In the United States there are currently two vaccines that can be used on ferrets, only one of which is USDA approved. In other countries of the world where there are no vaccines licensed for use on ferrets, dog canine distemper vaccines are commonly administered instead.

Waardenburg-Like Coloring

Ferrets with a white stripe on their face or a fully white head, primarily blazes, badgers, and pandas, almost certainly carry a congenital defect which shares some similarities to Waardenburg syndrome. This causes, among other things, a cranial deformation in the womb which broadens the skull, causing the white face markings but also partial or total deafness. It is estimated as many as 75% of ferrets with these Waardenburg-Like Colorings are deaf. Beyond that, the cranial deformation also causes a higher instance of stillborn ferret kits, and occasionally cleft palates. Because of this, many breeders will not breed Waardenburg-patterned ferrets.

Terminology and Coloring

A sable ferret, the most common color variation

Male ferrets are called hobs; female ferrets are jills. A spayed female is a sprite, and a neutered male is a gib. Ferrets under one year old are known as kits. A group of ferrets is known as a business.

Ferrets come in a variety of coat colors and patterns, the most common of which are as follows:

Colors: sable (the most common color) red-eyed white (albino) silver-mitt sterling silver white-footed sable butterscotch white-footed butterscotch cinnamon Panda(White head, stomach, tail and black torso and legs black-eyed white (BEW) aka dark-eyed white (DEW)

Color concentrations: point or siamese roan solid standard

Markings: blaze mitt

White ferrets were favored in the Middle Ages for the ease in seeing them in thick undergrowth, and ownership was restricted to those earning at least 40 shillings a year (a large sum then). Leonardo's painting Lady with an Ermine is likely mislabeled; the animal is probably a ferret, not a stoat, for which "ermine" is an alternative name (the latter strictly applying only to the animal in its white winter coat). Similarly, the "Ermine portrait of Queen Elizabeth the First" shows her with her pet ferret, who has been decorated with painted-on heraldic ermine spots.

Ferrets as pests

In 1877, farmers in New Zealand demanded that ferrets be introduced into the country to control the rabbit population, which was also introduced by humans. Five ferrets were imported in 1879, and in 1882-1883, 32 shipments of ferrets were made from London, totaling 1217 animals. Only 678 landed, and 198 were sent from Melbourne, Australia. On the voyage, the ferrets were mated with the European polecat, creating a number of hybrids that were capable of surviving in the wild. In 1884 and 1886, close to 4000 ferrets and ferret hybrids, 3099 weasels and 137 stoats were turned loose. Concern was raised that these animals would eventually prey on indigenous wildlife once rabbit populations dropped, and this is exactly what happened as New Zealand bird species had evolved free from mammalian predators.

Regulation on ferrets as pets

Australia

It is illegal to keep ferrets as pets in Queensland or the Northern Territory; in the ACT a license is required.

Iceland

Selling, distributing, breeding and keeping ferrets is illegal in Iceland.

New Zealand

It has been illegal to sell, distribute or breed ferrets in New Zealand since 2002.

Portugal

It is illegal to keep ferrets as pets in Portugal. Ferrets can only be used for hunting purposes and can only be kept with a government permit.

United States

Ferrets were once banned in many US states, but most of these laws were rescinded in the 1980s and 90s as they became popular pets. Ferrets are still illegal in California under Fish and Game Code Section 2118 and the California Code of Regulations.

Additionally, "Ferrets are strictly prohibited as pets under Hawaii law because they are potential carriers of the rabies virus"; the territory of Puerto Rico has a similar law.

Ferrets are also restricted by individual cities, such as New York City, Washington, DC, Beaumont, Texas, and Bloomington, Minnesota. They are also prohibited on many military bases. A permit to own a ferret is needed in other areas, including New Jersey and Rhode Island. Illinois does not require a permit to merely possess a ferret, but a permit is required to breed ferrets. It was once illegal to own ferrets in Dallas, Texas, but the current Dallas City Code for Animals includes regulations for the vaccination of ferrets.

Brazil

Ferrets are becoming popular. They are only allowed if they are given a microchip identification tag and sterilized.

Import laws

Japan

Although previously pet ferrets were allowed to be brought into Japan, that is no longer the case. Individual pet ferrets cannot be brought into Japan. However, licensed breeders such as Canadian Farms, PVF, Marshall's, etc... have a special agreement that still allows the import of those ferrets from those companies.

Canada

Ferrets brought from anywhere except the US require a Permit to Import from the Canadian Food Inspection Agency Animal Health Office. Ferrets from the US require only a vaccination certificate signed by a veterinarian. Ferrets under three months old are not subject to any restrictions for importation.

European Union

As of July 2004, dogs, cats, and ferrets can travel freely within the European Union under the PETS travel scheme. To cross a border within the EU, ferrets require at minimum an EU PETS passport and an identification microchip (though some countries will accept a tattoo instead). Vaccinations are also required; most countries require a rabies vaccine, and some also require a distemper vaccine and treatment for ticks and fleas 24 to 48 hours before entry. PETS travel information is available from any EU veterinarian or on government websites.

United Kingdom

The UK accepts ferrets under the PETS travel scheme. Ferrets must be microchipped, vaccinated, and documented. They must be treated for ticks and tapeworms 24 to 48 hours before entry. They must also arrive via an authorized route. Ferrets arriving from outside the EU may be subject to a six-month quarantine.

Australia

Ferrets cannot be imported into Australia at all. A report drafted in August 2000 seems to be the only effort made to date to change the situation.
